| contents | In recent years the James Webb Space Telescope has enabled the frontier of observational galaxy formation to push to ever higher redshift, deep within cosmic dawn. However, what is high-redshift, and when was cosmic dawn? While widely used, these terms (as well as many other confusing terms) are not consistently defined in the literature; this both hampers effective communication but also impedes our ability to precisely characterize and understand the phenomena under investigation. In this article we seek to address this issue of utmost importance. We begin by definitively defining terms such as ``high-redshift'', ``cosmic dawn'', etc. However, despite the rigorous definitions for them we present, both the adjective-based redshift and diurnal marker (time-of-day) division schemes suffer from issues including not being sufficiently granular, angering cosmologists, being arbitrary, and having a geocentric bias. To overcome these we introduce the \textit{redshiFt epOchs fOr everyboDy} (FOOD) framework, a revolutionary new division scheme based on eating occasions, i.e. meals. |
